Review: Maybe they could be thicker and leak proof--but their NOT diapers their male wraps to be used with Maxi Pads!! Or if your gonna be gone more than 5 hours stick a doggy diaper in it or better/cheaper baby diaper and hold in place with the wrap-Ive done this works too. This works great with maxie pads-NOT panty liners needs to be the fat pads. Depending on how much your dog pees-how long your gone-could leak through. They stay in place other reviewer dosent know what shes talking about. Chihuahuas wear xs-s (4-7pd) depending on weight. Just ordered M for my fat Chihuahua whose almost 9 pds. Diet time! No more marking my furniture and bedding when I'm not home!
